Alt. Title: 夢みた週末 / Yume Mita Shuumatsu
It started out as a way to prepare for a future lover. Too long denied a flesh and blood companion, his substitute—a teddy bear—is now his love object. What happens when a persistent, excessively cheerful neighbor consumes his serious, carefully ordered life? An explosion of hurtful, panicked words.
Stepping back into his quiet life, he can’t avoid what his insufferable neighbor left behind: cracks that expose his festering loneliness. Only one person can fill those cracks, but he’s disappeared.
